Played for a few days already (on the Free Demo version) and yet I had to download the game a second time because of an Assertion error that goes like so :
"Assertion failed: GetFName() == NAME_None [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/CoreUObject/Private/UObject/UObjectBase.cpp] [Line: 130]" - Copied from a Reddit Thread after searching for a way to correct the error without having to lose my files again.
As I understood it, it pops ups and crashes the game because an Object or Character hasn't been properly named. Should reread your code and check where the problem is, if the Patreon's version didn't already resolved the problem. By the way, is it normal to find a sprite-less Strange Fruit in the Sewer Dungeon ? 'Cause I did and the error popped up a few minutes after selling it to a shop.
